Title: Oil component detector
Inventor: WATANABE MASAHIRO
IPC: G01N27/06
Filed: 1990-09-08
Abstract: PURPOSE:To detect insufficiency of additive at a stage of injecting new oil by heating oil to be detected into an oil guiding means to a predetermined temperature, receiving a signal from a signal outputting means which outputs a signal according to electric conductivity and comparing a detection value based on the signal with a reference value. CONSTITUTION:When oil is injected into an engine, oil to be detected is led between a pair of metal plates 11,12 and also heated to 100 deg.C or higher by a heater 15, wherein due to difference in adsorption to metal by anti-friction agent, good oil is maintained between the metal plates 11,12 while bad oil will flow out. Thus there is difference in voltage signals of good oil and bad oil, so that comparison of a detection value with the voltage signal of a signal outputting means 16 with a reference value by a determining means 21 permits determination as to whether the oil to be detected is good or bad. Thus by making determination at a stage of injecting new oil, problems due to use of bad oil with a small amount of additive can be prevented.

Title: Fast tuning filter
Inventor: TAKAHASHI YUJI
IPC: H01P1/205
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To eliminate the linear disturbance of the filter tuning frequency control and to improve the selectivity of a radio unit by preparing a 2nd inductance element to cancel the capacity generated when all PIN diodes are turned off. SOLUTION: Every PIN diode 8 which is placed on a short-circuit surface is connected to the tip of every element 7 attached to every internal conductor 1. In such a constitution of this resonator, the capacity generated when all diodes 8 of the inductance elements connected in parallel to the LC parallel resonance circuits are turned off is canceled by every rod-shaped or plate-shaped element 9 that is connected to the short-circuit surface from an optional position of the conductor 1. Thus, the deterioration of Q of the resonator is prevented. The capacity that is caused at every inductance element when every diode 8 is turned off is canceled by a rod-shaped or plate-shaped element 10 which is connected between every external conductor 2 placed at a position corresponding to the tip of every diode 8 and a part of the short-circuit surface where the diodes 8 are placed.  As a result, the filter tuning frequency control can be linearly corrected.

Title: Method and apparatus for polishing
Inventor: WATANABE JUNJI
IPC: B24B37/00
Filed: 1985-10-28
Abstract: PURPOSE:To avoid direct contact between the surface to be machined and the polisher surface and prevent mechanical damage to the surface to be machined by forcibly feeding polishing agent from the lower surface of the polisher having through holes and imparting a lift to the workpiece due to the squeeze effect for polishing. CONSTITUTION:As a rotary disc 12 is rotated around the shaft 16 in the direction of an arrow, polishing agent is supplied from a nozzle 13. The polishing agent 3 sprayed from the tip end 131 of the nozzle 13 passes through a channel 122 as shown by arrows and is quickly fed toward the outer peripheral portion due to rotational centrifugal force. As the channel 122 is closed at its outer peripheral end, the polishing agent 3 goes through minute through pores in the polisher 11 up to the upper surface of the polisher 11, so that a quite small space is defined by the squeeze effect between the surface to be machined and the polisher surface. As particles in the polishing agent lie over the whole space, there is no fear of direct contact between minute projections on the polisher surface and the surface to be machined, preventing any mechanical damage to the surface to be machined.
